Polyquaternium-11

INCI Name

Polyquaternium-11

CAS Number

53633-54-8

Product Description

Polyquaternium-11 is a cationic film-forming conditioning polymer used to improve slip, manageability, anti-static performance, and style support in haircare and cleansing systems. It forms clear, non-tacky films that condition without excessive buildup and can also enhance sensory feel in select skin and body products. High-Viscosity Concentrate (Cosmetic Grade)

Important: This grade is not the thin “regular” version

This product is supplied as a high-viscosity concentrate, so it will look and pour much thicker than many commonly sold Polyquaternium-11 solutions (which are often offered pre-diluted). High viscosity is normal for concentrated Polyquaternium-11 solutions.

Concentrated yield (why 2 oz goes further)

Because this is a concentrated, high-viscosity grade, 2 oz can be diluted to make up to 16 oz of a working solution similar to what many customers buy elsewhere (final dilution depends on the thickness/concentration you want to match).

Example working solution:
2 oz concentrate + 14 oz distilled water = 16 oz working solution

How to Use (customer-friendly)

Option A — Use as-is (concentrate)

Add directly to your formula during the water phase or cool-down (best practice depends on your system). Polyquaternium-11 is commonly used in shampoos, cleansers, conditioners, gels, sprays, and styling products.

Option B — Pre-dilute for easier measuring

To make it easier to handle and measure, pre-dilute into a “working solution” using distilled water. Mix slowly to reduce bubbles and allow time for full blending.
